After the deluge of announcements last year, 2022 will see the trickle of big batteries actually operating in Australia turn to a flood. According to Rystad Energy, the country’s battery capacity is set to double before the year is out.

As Australia’s federal election looms, the Clean Energy Council has released a set of nine policy suggestions to realise not only Australia’s decarbonisation, but its potential as a clean energy superpower. The suggestions range from electrifying everything, allocating $1 billion to transition coal communities, and setting hydrogen blending targets for gas networks.

Researchers from Finland and Sweden have reviewed different ways to store compressed gaseous hydrogen, including storage vessels, geological storage, and other underground options.

Standalone power systems utilising solar PV and battery technology continue to gain traction in the Australian market with New South Wales Government-owned network service provider Essential Energy announcing it will seek input from customers living at the “edge of the grid” as it seeks to expand its roll out of the off-grid technology.

Thai-owned Ratch Australia has revealed plans to develop a 70 MW solar PV and large-scale battery energy storage project in the heart of Victoria’s coal country after receiving planning approval from the state government for the $105 million Morwell Solar Farm.

Renewable energy investors’ appetite for large-scale development in Australia appears far from sated with the New South Wales Government revealing almost 50 new solar PV, wind and energy storage projects, totalling more than 34 GW, have been proposed for the South-West Renewable Energy Zone.

Conceived by scientists in China, the device combines an integrated carbon-based perovskite solar cell module with a rechargeable aqueous zinc metal cell. The proposed system achieved an overall efficiency of 6.4%, and a steady operation for more than 200 cycles with little performance degradation.

The Western Australian coastal town of Kalbarri can now be powered by an entirely renewable energy solution utilising rooftop solar and wind generation coupled with battery storage with state government-owned utility Western Power confirming the state’s largest renewable energy microgrid has been commissioned.

The uptake of EVs in the years ahead will add up to staggering battery capacity, mostly sitting idle on driveways. The two-way flow of electricity from EV batteries, known as vehicle to grid, could not only enable power systems to rely on intermittent renewables, but could also be the trump card for network operators to respond to grid disturbances. However, there are still a few catches to be worked out, as Marija Maisch explains.

Green hydrogen is being proposed for an ever-wider variety of uses. While some of these are still a way off, others make little sense. But there are sectors where demand for green hydrogen is a reality today, writes Christian Roselund.
